I decided to test compile a project with -Wsign-conversion enabled, to see what warnings would come up, and came across something that doesn't seem right, where gcc behaves differently than clang. Can someone please tell me which is correct?
I have a function that takes a size_t param:
void func(size_t) {}
some other struct
struct Test {};
and calling code
int i = some_initialiser();
func(sizeof(Test) + static_cast<size_t>(i));
So from my understanding, sizeof returns size_t, and arithmetic between two variables …
